' LOOSE LEAF BINDER Application filed April 17,

My invention relates to the binding art and particularly to devices for receiving and filing loose sheets in a book form in which means are provided for the easy removal of a single sheet or a plurality of sheets without those remaining in the binder being separated or displaced from their order. My invention has for its principal object to produce such a device in a simple, strong, dlpar- LY invention has for its further object to provide a quickly detachable sheet bar which can be removed carrying with it one or any desired number of sheets from those in the book Without disturbing their order; My

, foregoing objects may be more readily unders ood by having reference to the accompanying drawings, in which- Fig. 1 is an isometric perspective view of a binder equipped with my improvement;

Figs. 2 and 3 are perspective views show- Fig. 4 is a detail view of the lock bar;

Fig. 5 is a detail view of onefof the binder posts; I

Fig. 6 is an isometric'perspective view of the binder open. the extended position being shown in dotted lines; 2

Fig. 7 is a perspective view of the lock bar; and

Fig. 8 is an enlarged detail plan view of the lock bar in position.

My binder consists of lower and upper covers 10 and 15. The cover 10 is attached by means of a hinge 11 to an L-shaped member 12, the hinge being at the angle portion of the L,v as shown. The vertical portion ofthe L-shaped member is designed to slidablv engage the vertical portion of a similar L-shaped member 13, also hinged, as shown at 14. to the upper cover 15, thereby forming a back for my binder, when the parts are joined. as hereinafter set forth.

To the inner surface of the short or horizontal side of the L-shaped member 12 I have secured a plurality of sheet receiving posts 16, these posts preferably being built 1928. Serial No. 270,684.

up of removable sections,'as seen in Figure 5, one post being preferably located at the center of the said L-shaped member. The said posts are in perfect alinement and, are parallel to, and spaced from the vertical portion of the L-shaped member 12.

My detachable sheet bar 17 is removably positioned on the said L-shaped member 12, in the following manner: The sheet bar is provided near each end, with a downwardly projecting post,'18 and 19, respectively, exactly similar in every respect to the posts 16. Ont-he upper side of the said sheet bar, preferably near each end, I have provided lugs, 20 and 21 which register with openings 25 and 26 formed in the horizontal portion of the upper L-sha ped member 13. In the center of the sheet bar 17 I have provided an opening 22, to receive the end of the central post. 16. To the upper end of the said central. post 16 I have secured a headed lug 23, for purposes hereinafter set forth. 7

The shorter portion of the L-shaped mem ber 13 is provided with orifices 24 and 25, whichreceive the lugs 20 and 21 and in the center thereof I have provided an orifice 26,

toregister with the orifice 22 to receive, and perm t to-pass therethrough, the headed lug 23. On the upper surface of the said shorter portion of the L-shaped member 13, I have mounted, for slidable movement, a lock bar' 27. which has a bifurcated end the forks of.

ing upwardly and holding the filed sheets between them. When the parts of my device are locked tog-etherthe longer portion of one of the L-shaped members overlies and contacts the longer portion of its mating L- shapedmember. V p

In practical operation the sheets to be filed are punched and threaded on the posts 16. The sheet bar 17 is then positioned, the posts 18 and 19 passing through prepared orifices in the sheets and their ends contacting the inner surface of the shorter portion of the L-shaped member 12, the headed lug, or stud, 23 projecting upwardly through the orifice The upper cover is then'placed in position, the lugs 20 and 21 engaging the orifices 2 and 25, respectively, and the headed lug 23 projecting throusrh the orifice 26. The

lock bar 27 is then pushed inwardly until its bifurcated end engages under the head of the headed lu 23, and the parts of my binder are securely locked together and firmly bind the filed sheets in the binder. V hen it is desired to remove or insert additional sheets, by sliding the lock barQT outwardlv the forks oi the biturcated end disengage with the headed lug 23, when the upper cover 15 can be lifted asshown .in the dotted lines in Fig. 6. This leaves the sheet bar 17 free and it can be removed for the purpose of adding additional sheets tothe volume or if it is desired to remove a sheet orinsert one or more in the central portion of the volume theisheet bar is liftedjust'enough topermit the desired sheets remaining on the posts Band 19 so that they cannot get out of order, wh le the remaining sheets'will be held in place'by the postsl6 and 23.

Having thus described'my invention what I claim and desire to secure by Letters Patent of the United States is:

1.- A loose leaf binder comprising upper and lower cover members, L-shaped members hinged to each ofthe cover members. said hinges being positioned at the angle of each L,.the horizontal portion of the upper .L having a plurality of orifices formed there n. a]
